This write-only-in-practice value, when set, adds all currently learned ARP table entries to the static IP source guard binding table, with reading it back being meaningless. An admin triggers this to quickly convert the switch's dynamically learned ARP entries into permanent static bindings, for example when locking down a network after initial device discovery. For example, an admin would set this object once all expected devices have populated the ARP table, converting that snapshot into static bindings that resist future ARP spoofing.
